Knowledge Without Vision?

There are some really intelligent people but they don't use their intelligence. They have all the skills they need to make a miracle and to make a huge success in their lives. But, they don't see it. They don't lay awake at night imagining what their life could look like if they applied one incredible idea from their heads. Because they don't have any ideas. On the other hand, there are people with big dreams and visions which seem crazy to other people. They don't have all of the skills they need but their visions are pushing and motivating them to learn and eventually, they make huge things in their lives. They become rich, successful people because they accept the fact that their skills aren't the best but their dreams are so they can easily hire someone who is extremely intelligent to work for them, but the profit is mostly for the ones with visions and big dreams. So, now I am asking you, what is more important? To have a big dream and vision in your head that makes you push harder every day and to never stop, or to have an intelligent mind although you don't use your abilities and skills?
